Definitions:

Null Hypothesis

The null hypothesis is a statement used in statistical testing that proposes there is no significant difference or effect, serving as the default assumption to be tested against.

Level of Significance

The threshold below which a p-value is considered statistically significant, typically set at 0.05 or 5%, indicating the probability of rejecting the null hypothesis when it is true.

Point Estimate

A single value (statistic) given as the best guess or most reasonable approximation of a population parameter based on sample data.

Population Proportion

The fraction or percentage of members in a population that exhibit a particular characteristic or attribute.
